基于模糊控制的PWM整流器电压调速策略
Fuzzy control based voltage regulation strategy for PWM rectifier
摘要
Abstract
In response to the issue of the direct current(DC)voltage response rate in the control system of three-phase pulse width modulation(PWM)rectifier,a fast voltage response control strategy based on fuzzy control is proposed.The mathematical model of PWM rectifier in a qd coordinate system is established,the underactuated characteristics are analyzed and the control strategy is studied,and a cascaded dual closed-loop control structure is designed.The inner current loop controller is designed by using a partial feedback linearization strategy and a fuzzy control strategy for the outer voltage loop is proposed to improve the DC-side voltage response speed.The proposed control strategy is able to achieve stabilization within 0.05 s with a power factor of 0.99,which improves the system's disturbance immunity.The simulation results prove the effectiveness of the designed control scheme.关键词
